Abstract
Some implementations can include a method including reserving a range of multicast addresses for handling link-local multicasts and generating a multicast group within the range for each VLAN. The method can also include subscribing at an access point to a corresponding multicast group for a VLAN when a client associates with the access point, and tunneling link local multicast traffic from the client to a WSP component via an access tunnel. The method can further include forwarding the link local multicast traffic from the WSP component to subscribing access points.
Claims20
A method comprising:
- reserving a range of multicast addresses for handling link-local multicasts within a network;
- generating a multicast group within the range for each VLAN;
- subscribing at an access point to a corresponding multicast group for a VLAN when a client associates with the access point;
- tunneling link local multicast traffic from the client to a WSP component via an access tunnel;
- and
- forwarding the link local multicast traffic from the WSP component to subscribing access points.
A system comprising one or more processors configured to perform operations including:
- reserving a range of multicast addresses for handling link-local multicasts within a network;
- generating a multicast group within the range for each VLAN;
- subscribing at an access point to a corresponding multicast group for a VLAN when a client associates with the access point;
- tunneling link local multicast traffic from the client to a WSP component via an access tunnel;
- and
- forwarding the link local multicast traffic from the WSP component to subscribing access points.
A nontransitory computer readable medium having stored thereon software instructions that, when executed by a processor of a wireless controller, cause the processor to perform operations including:
- reserving a range of multicast addresses for handling link-local multicasts within a network;
- generating a multicast group within the range for each VLAN;
- subscribing at an access point to a corresponding multicast group for a VLAN when a client associates with the access point;
- tunneling link local multicast traffic from the client to a WSP component via an access tunnel;
- and
- forwarding the link local multicast traffic from the WSP component to subscribing access points.
